VMware vCloud Director 5.1 Evaluation Guide

When enabled to get what they need quickly and easily, end users are more likely to make more realistic

resource requests and to return the resources when ﬁnished.

The transition to virtualization began with speciﬁc workloads. The evolution into the cloud also begins in this

manner. To start, identify workloads that have a low management or governance need and that are required

frequently. A good source for this type of workload is testing and development or preproduction environments.

For example, in a typical development environment, multiple developers often require similar environments for

short periods of time. These environments can be hosted in a virtualized environment, though they tend to

require refreshes as new product releases are made. This continual need to create environments for the

developers and to manage them after they are created can place a large burden on the IT sta of an

organization. By shifting to a self-service model for these workloads, an IT sta can save considerable time while

also using this experience to hone its capabilities to deliver IT as a service (ITaas).

Although the ﬁrst step in the journey to the cloud might involve low-governance workloads, they are not the

ultimate goal. A private cloud solution can meet the needs of many applications and provides users with new

ways of looking at how applications and services are provided and utilized.

As an example, consider a typical ERP system, which tends to have long development cycles with fairly minimal

changes. A private cloud certainly will help in the development eort by provisioning resources on demand.

Because this can be done so quickly, end users can also perform actions that previously were considered

dicult. They can quickly test new applications or deploy new analytic packages. If successful, they can examine

the feasibility of incorporating them into the ERP solution. If not, it’s a simple matter to destroy the environment

and provision a new one, with no trace of the new software.

The agility provided by a private cloud is not solely about how quickly one can deploy something. It is also about

how quickly one can test something—and tear it down if it fails. Not trying something simply because it would

cost too much in time and personnel resources is not a viable excuse any more.

The journey to the private cloud mimics the journey to virtualization in another critical way. As companies

moved from virtualizing low-impact applications to doing so with more business-critical ones, the capabilities

provided by virtualization were changing the way they deployed and managed applications. The zero-downtime

migration capabilities of vMotion and failure handling of vSphere HA meant clustering between multiple running

systems no longer made sense. The shift to a more agile infrastructure will drive similar changes. Business

applications that might be considered as having a low frequency of change might very likely be reexamined in

the light of the capabilities of a private cloud. Applications will remain mission critical, but the concept of making

routine changes to better support the business will become far less daunting.

Understanding the VMware vCloud Suite

The VMware vCloud Suite is a combination of products designed to enable an IT organization to build and

manage a private cloud based on a vSphere environment. The product suite consists of several components,

including the following:

VMware vSphere is the industry-leading virtualization platform and enabler for cloud computing architectures.

vSphere enables IT to meet SLAs for the most demanding business-critical applications, at the lowest TCO.

VMware vCloud Director provides the automation and user portal capabilities needed to enable self-

provisioning and management of workloads across one or more vSphere environments. This enables businesses

to migrate gradually to cloud computing while continuing to leverage existing vSphere investments.

VMware vCloud Networking and Security – Dynamic virtual and cloud infrastructure requires an integrated

approach to networking and security. With this goal in mind, VMware oers these capabilities in a single

solutioncalled VMware vCloud Networking and Security, which incorporates the capabilities of VMware vShield

Edge™ and VMware vShield™ App with Data Security while oering many additional features and

enhancements. These include VXLAN; a more ﬂexible load balancer; performance, usability and high-availability

enhancements to vShield Edge; and VMware vCloud Ecosystem Framework for third-party integration.
